Investigating how cannabis affects the blood-brain barrier in people with HIV

Cannabis and Pathogenic Mechanisms influencing Blood Brain Barrier Function in HIV

NIH-funded research University of California, San Diego · NIH-10898883

This study is looking at how using cannabis might affect the brain's protective barrier in people living with HIV, to see if moderate use could help protect the brain while heavy use might cause problems.

What this research studies

This research explores the impact of cannabis use on the blood-brain barrier (BBB) in individuals living with HIV. It combines clinical observations with advanced laboratory models to assess how different patterns of cannabis use may influence BBB integrity, inflammation, and mitochondrial health. By analyzing biomarkers in blood and cerebrospinal fluid, the study aims to determine whether moderate cannabis use can provide protective benefits against BBB damage, while chronic use may have harmful effects. The findings could lead to better understanding and management of neurocognitive complications in people with HIV.

Who could benefit from this research

Good fit: Ideal candidates for this research are individuals living with HIV who use cannabis, ranging from occasional to daily users.

Not a fit: Patients who do not use cannabis or those without HIV may not benefit from this research.

Why it matters

Potential benefit: If successful, this research could lead to improved treatment strategies for neurocognitive impairments in people with HIV.

How similar studies have performed: Previous research has indicated potential protective effects of cannabis on the blood-brain barrier, but this study aims to explore this relationship in a more comprehensive and systematic manner.
